Patented Mar. 11, 1930 UNITED STATES WILLIAM M. CONNOR, OF BALTIMORE, MARYLAND, ASSIGNOR TO AMERICAN TIN COMPANY, INC., OF BALTIMORE, MARYLAND, A CORPORATION DEEP-METAL REFINER Application filed February 12, 1929. Serial No. 339,416.

My invention relates to an implement for use in the treatment of metals although not necessarily restricted to this use.

An important object of my invention is the provision of a tool for use in treating a bath of molten metal.

Another object of my invention is to provide a device of the above mentioned character which is simple of construction and operation, inexpensive to manufacture, strong and durable.

Other objects and advantages of my invention will be apparent during the course of the following description.

In the accompanying drawings, which form a part of this speclfication, and wherein like characters of reference denote like or corresponding parts throughout the same,

Figure 1 is a front elevation of an implement embodying my invention,

Figure 2 is a vertical central section therethrough,

Figure 3 is a horizontal section on the line 33 thereof,

Figure 4 is an elevation of one of the end caps,

Figure 5 is an elevation of a modified form of implement on a larger scale than Figure 1, and

Figure 6 is a vertical sectional view thereof.

In the drawings wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral 10 designates the tubular open ended body portion having a centrally arranged screwthreaded boss 11 on its top for the reception of an elongated rod or handle 12 provided with a suitable loop or grip 13 at its end.

A suitable lock nut and washer 14 are'provided to secure the rod 12 in place. A second and larger boss 15 is arranged on the side of the tubular body portion 10, centrally and is provided with a screwthreaded inlet opening 16 normally closed by a screwthreaded plug 17. The plug is preferably provided with wings or with an operating rod 18, as shown, to facilitate insertion and removal thereof.

The ends of the tubular body portion 10 are exteriorly screwthreaded to receive elongated end or cap members 19. The cap members are interiorly screwthreaded to engage the ends of the body portion, and are strengthened by end flanges 20. Suitable longitudinally extending'ribs 21 may be provided to facilitate rotation of the cap members.

The faces of the caps 19 are provided with suitable perforations 22 which are shown as arranged in a circle, but may be arranged in anysuitable manner. Each cap is provided with a wad or filling of foraminous or fibrous material 23 such as mineral wool. Then the caps are screwed into place, the wads or fillings 23' are held in place" in the caps by the ends of the tubularbody por-' tion 10, as shown in Figures 2 and 3.

In operation, any suitable metal treating compound or solution is inserted in the body portion 10 through the opening 16, the plug 17 is secured in place and the implement is plunged beneath the surface of a bath of molten metal and agitated. The solution is prevented from running out of the perforations 22 by thewads 23 but when the tool is used to agitate the bath of metal,-the solution seeps outinto the metal and is mixed therewith. lVhen the solution is exhausted,

the implement is removed and any molten metal which has found its Way through the perforations 22may be shaken out.

Vhile this implement is very useful in deoxidizingor refining a bathof molten metal it is obvious that it may be'used for other.

purposes. In treating metal, the tool isheld adjacent the bottom of the crucible and moved violently back and forth, by means of the handle -12, and the solution seeps out-and bubbles up through the metal. The operator can determine when the solution is ex hausted by watching the metal. Vhen ebullition ceases, the implement is removed, and

ifffurther treatment is desired, may be, re-

filled and the process repeated.

' In Figures 5 and 6 I have illustrated a smaller tool for usein treating the metal in the metal wells of linotype or similar ma- .chines. In this form of the invention, a

cylindrical body portion 10 is exteriorly screwthreaded and provided with a post or boss 11 which has a'central screwthreaded Opening or bore to receive the threaded lower material arranged in said caps and adapted end of a handle or rod 12. The upper end of to impede the rod 12 is bent over at a right angle to tl OUghform a grip 13 and a nut lat is provided to lock the handle in the boss 11. The lower end of the body portion is recessed at 15 to provide a chamber for the solution to be used. A cap member 19, relatively longer than the caps 19, is interiorly threaded and adapted to be screwed on to the body portion 10. Suitable perforations 22 are arranged in the sides of the cap 19 adjacent its lower end, and a strengthening flange or bead 20 is provided at the top of the cap. Ribs 21 may be provided to facilitate rotation of thecap.

A wad or filling 23 of fibrous or similar material such as mineral wool is arranged within the cap and is pressed against the lower end of the body 10 as shown in Figure 6.

In operation the deoxidizing, refining, or other compound or solution is placed in the recess 15 or in the cap 19, the cap is screwed onto the body 10 and the implement is plunged beneath the surface of the bath in the linotype well or other receptacle and moved vigorously about. The operation is the same as that of the tool shown in Figures 1 to 4.

The implement shown in Figures 5 and 6 is very effective in cleaning the throats and mouthpieces of linotype and other typesetting machines because it is a means of injecting a purifying or deoxidizing agent therein. The tool can be made in various sizes to accommodate different makes of typesetting machines, and may also be put to various other uses.

Vhile I have shown and described the preferred form of my invention it is to be understood that various changes in the size, shape and arrangement of parts may be resorted to without departing from the spirit of my invention or the scope of the subjoined claims.

Having thus described my invention, what I claim and desire to protect by Letters Patent is:

1. A device of the character described comprising a tubular body portion, a handle member secured thereto, said body portion being adapted to receive a fluid, and having an inlet opening, means to close said inlet opening. perforated caps secured to the ends of said tubular body portion, and wads of fibrous material arranged in said caps andadapted to impede the flow of fluid therefrom.

2. A device of the character described comprising a tubular body portion having its ends open, an elongated handle member secured thereto, said body portion being adapted to receive a liquid, and having an inlet opening therein, means to close said inlet opening, removable, perforated caps adapted to close the ends of said tubular body portion, and wads of a fibrous, non-combustible the flow of the liquid there- In testimony whereof I afiiX my signature.
